Could you run with -X:ExceptionDetail and report back the stack trace? That'll let us know where the exception is actually coming from.

Loading a CPython interpreter through the Python.NET assembly seems to change the IronPython (2a5) import machinery. I have a test module 'xyzz.py' that has an unused name 'wibble'. Unsurprisingly, attempting to import this into IronPython 2.0a5 raises a name error: IronPython console: IronPython 2.0A5 (2.0.11011.00) on .NET 2.0.50727.1378 Copyright (c) Microsoft Corporation. All rights reserved. >>> import xyzz Traceback (most recent call last): File , line 0, in ##7 File , line 0, in _stub_##2 File C:\compile\cext\trunk\cext\xyzz.py, line 1, in Initialize NameError: name 'wibble' is not defined Executing the following code, (using the 'Python.Runtime' assembly from Python.NET with Python 2.4): IronPython console: IronPython 2.0A5 (2.0.11011.00) on .NET 2.0.50727.1378 Copyright (c) Microsoft Corporation. All rights reserved. >>> import clr >>> clr.AddReference('Python.Runtime') >>> >>> from Python.Runtime import PythonEngine >>> engine = PythonEngine() >>> engine.Initialize() >>> >>> import xyzz Traceback (most recent call last): File , line 0, in ##18 File , line 0, in _stub_##2 File mscorlib, line unknown, in DefineDynamicAssembly File mscorlib, line unknown, in InternalDefineDynamicAssembly TypeError: Unable to cast object of type 'System.Reflection.Module' to type 'Sys tem.Reflection.Emit.ModuleBuilder'. Just importing the 'PythonEngine' isn't enough. The problem only happens if the PythonEngine is instantiated and initialized.
